HSS step cone drill titanium plating drill bit hole cutter, hss steel with titanium coated to reduce friction and heat. Which is used to cut thin iron plate, aluminum material, wood,copper plate, pvc plate.Thickness within 5mm. Key feature: 1.Ultra durable, high quality HSS steel with Titanium coated, Titanium coated to reduce friction and heat. 2.The depth gauge design and dual slot makes it smoother, faster and even more accurate during cuts 3.Laser sizes: In order to avoid the problem of wear and tear after being used repeatedly, sizes are usually laser etched in the metal. 4.Unique step structure make it possible to open various size of holes. Specification: Material: HSS steel with Titanium Plated Shank Type: Round Shank Color: Silver Models: 5-35mm Shank Diameter: 13mm Hole Sizes: 5 mm, 7 mm, 10 mm, 12 mm, 15 mm, 17 mm, 20 mm, 22 mm, 25 mm, 27 mm, 30 mm, 32 mm, 35 mm (13 steps) Packing: 1 * Step Cone Drill, Opp bag packaging Note: When you use this drill bits, high temperature will be generated, please add some water or coolant to avoid the material get smoke when using it.
Drill size: Sizes are laser etched into the metal. This is to ensure they don’t wear out even after being put to use repeatedly, make precise drilling easy. 13 hole sizes: 5 mm, 7 mm, 10 mm, 12 mm, 15 mm, 17 mm, 20 mm, 22 mm, 25 mm, 27 mm, 30 mm, 32 mm, 35 mm. This step drill bit meets the need to machine holes of different diameters. Easy to Drill: Two-fluted to ensure drilling faster and also smoother. Through the surface depth gauge, drilling becomes very precise and accurate. Quickly removes chips and deburrs the hole, the pressure is small, drilling and cutting are faster and smoother. High temperature will be generated in the work project, and water or coolant needs to be added to cool the drill bit. Top Quality Material: This step drill bit is made of high speed steel material, which has high wear resistance, high toughness and high strength flexibility. Titanium coated to reduce friction and heat, makes the drill more durable and longer lasting. Compatible models: Suitable for lithium electric drills, hand drills, bench drills, etc. It is recommended to use 36v and 48v lithium electric drills. The larger the diameter of the hole that needs to be opened, the lower the rotating speed of the electric drill, and the recommended rotating speed is within 1000RPM. Wide Usage: This drill bit is used to cut thin iron plate, aluminum material, plastic, thin iron, wood board, copper plate, PVC plate.Thickness within 5mm. Not suitable for carbon steel, stainless steel and ceramic tiles. Note: Please use in the specified plate to avoid damage to the drill.
